GlobalFoundries acquires Advanced Micro Foundry to expand silicon photonics AI infrastructure portfolio
GlobalFoundries of Malta, NY (GF, the only US-based pure-play foundry with a global manufacturing footprint, including facilities in the USA, Europe and Singapore) has announced the acquisition of commercial pure-play specialty silicon photonics foundry Advanced Micro Foundry Pte Ltd (AMF) – a spin-off of the Institute of Microelectronics (IME), a research institute of Singapore’s Agency for Science, Technology and Research (A*STAR) – marking what is described as a pivotal step in GF’s strategy to advance innovation in silicon photonics. The acquisition will expand GF’s silicon photonics technology portfolio, production capacity and R&D in Singapore, complementing its existing technology capabilities in the USA and unlocking new market opportunities with a broader set of data-center and communication technologies.
The acquisition brings together AMF’s manufacturing assets, extensive intellectual property and skilled labor to significantly expand GF’s silicon photonics technology and establish it as the largest silicon photonics pure-play foundry by revenue. Leveraging over 15 years of AMF’s manufacturing expertise, GF will address demands in long-haul optical communications, computing, LiDAR and sensing on AMF’s 200mm platform in Singapore, with plans to scale to 300mm as market needs grow, ensuring reliable global supply for AI data centers, communications and next-generation applications.
As GF continues to expand its US manufacturing capacity for silicon photonics in New York, the acquisition accelerates the ramp of GF’s Singapore operation, enhancing supply chain resilience and enabling customers to source secure, differentiated solutions from multiple geographies.
“Silicon photonics technology is essential for AI infrastructure. As data moves faster and workloads grow more complex, the ability to move information with greater speed, precision and power efficiency is now fundamental to AI data centers and advanced telecom networks,” says GF’s CEO Tim Breen. “Acquiring AMF enables GF to deliver an expanded, and differentiated, decade-long roadmap for pluggable transceivers and co-packaged optics, while accelerating growth of photonics into adjacent markets such as automotive and quantum computing.”
In line with the acquisition, GF plans to establish a silicon photonics R&D center of excellence (CoE) in Singapore. This will partner with A*STAR to advance GF’s innovation roadmap by focusing on next-generation materials for ultra-fast data transfer at 400Gbps speed. This collaboration should enhance the company’s silicon photonics platform to provide high-performance, secure data-transfer solutions to customers worldwide.
“AMF and GF share a vision of innovation and close customer partnerships to deliver differentiated solutions,” says AMF’s CEO Jagadish CV. “With complementary technology portfolios, we are proud to join forces with a trusted manufacturer with global reach and, together, look forward to advancing silicon photonics technology for a broader range of markets and customers.”
